The transport network layer is built on IP transport and GTP-U is used on top of UDP/IP to carry the user plane PDUs between the NG-RAN node and the UPF. While the split between CU and DU is now formally defined by 3GPP, there are a number of split options still to be considered for the DU/RU interface, which we will explore later. According to different service requirements, fiber/optic cable availability and network resource allocations, RAN real time and non-real time resources can be deployed on the site or on the access cloud side. The 5G Architecture Working Group as part of the 5GPPP Initiative is looking at capturing novel trends and key technological enablers for the realization of the 5G architecture.
